Can't control SPI_CS_HIGH
I am running Linux on Omap 3530. I have a development kit from LogicPD (LV SOM). I need to use /dev/spidev3.0. I followed the test code in from Linux Kernel Documentation :: spi : spidev_test.c. It appears working except for the Chip Select signal. The default should set the cs to Active Low. But it stays high all the time. I tried to set SPI_CS_HIGH but CS signal just won't toggle during transmission.
ANy advice or suggestions would be appreciated.
